AKAP18δ Anchors and Regulates CaMKII Activity at Phospholamban-SERCA2 and RYR.

Abstract
:

The sarcoplasmic reticulum (SR) Ca-ATPase 2 (SERCA2) mediates Ca reuptake into SR and thereby promotes cardiomyocyte relaxation, whereas the ryanodine receptor (RYR) mediates Ca release from SR and triggers contraction. Ca/CaMKII (CaM [calmodulin]-dependent protein kinase II) regulates activities of SERCA2 through phosphorylation of PLN (phospholamban) and RYR through direct phosphorylation. However, the mechanisms for CaMKIIδ anchoring to SERCA2-PLN and RYR and its regulation by local Ca signals remain elusive. The objective of this study was to investigate CaMKIIδ anchoring and regulation at SERCA2-PLN and RYR.
